EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 265,349, dated October3, 1882.

Application filed February 18, 1882.

To all whom it may concern:

Be it known that I, JOHN 0. Warren, a citizen of the United States,residing at Indianapolis, in the county of Marion and State ofIndiana,have invented certain new and useful Improvements in ExtensionTables, of which the following is a specification, reference being badtherein to the accompanying drawings.

My invention relates to improvements in folding or extension tables; andthe object of my improvements is to provide novel combinations ofdevices for holding the parts in position when they are in theirextended position, and also when they are folded up. I attain thisobject by the devices and combinationsillustrated in the accompanyingdrawings, in which Figure 1 is a bottom view, showing the positions ofthe parts as they appear when folded up. Fig. 2 is a sectionalelevation, showing the leaves, the legs, and the dogs or hooks forholding the parts in position. Fig. 3 is aplan view of the lower side ofthe table as it appears when extended, and showing the sliding frame forholding up the end leaves. Fig. 4 is a longitudinal sectional elevation,showing the position of the parts when extended, and Fig. 5 is atransverse section on line 00 x x w xof Fig. 4.

Similar letters refer to similar parts throughout the several views.

It is desirable that extension-tables at which a large number of peoplecan be seated when extended should be capable of being folded into sucha position as to occupy the smallest possible amount of room when not inuse; and the design of my present invention .is to accomplish thisresult, in doing which I provide two principal leaves, A A, to the undersurfaces of which frames A A are firmly secured, to which the legs A Aare attached. A, is attached to the frame A across which it extendstransversely, it being provided at its center with an opening, A",through which passes a bar, A the outer end of which is provided with astop,A which limits its movement as it is moved inward by coming incontact with the bar A. The inner end of bar A is firmly secured to asliding leg B, the upper end of which is attached to a bar, B, whichmoveslon gitudinally in guides B andB ,formed A bar,

(Model) upon the under surface of the leaf A, as shown in Fig. 3.

To the inner end of the sliding bar A there is pivoted a leaf-supporter,B, which I prefer to make of metal, but which may be made of wood, ifdesired, it consisting of bars pivoted to the slide in such a manner asto turn freely on the pivotal points, in order that when the table isfolded up, as shown in Fig. 2, they may be placed in avertical position,in which they are out of the way of the folding leaves. When the tableis extended to its full limit the bars B, which are united at theirinner ends by any suitable device, are turned up into the position shownin Fig. 4, at which time they form supports for the leaves B B, and Bwhich intervene between those lettered A A.

For the purpose of holding the bars B in their elevated positions thereis attached to them at B two curved bars, B, the outer ends of which areunited by a cross-bar, and kept at such a distance apart that one ofthem passes along each side of the leg B, in the sides of which thereare secured pins or bolts, with which a notch formed in the curved barengages, and so holds the support B in its elevated position, as shownin Fig. 4, a spring,

B being secured to the side of the leg B, which acts upon the cross-barwhich unites with the curved bars B and thus forces them down when uponthe pins'in the leg.

In order that the leaves .8 may be properly supported upon the leaves AA, and yet allowed to be folded down against the legs B and the supportsB as shown in Fig. 2, they are hinged to a sliding frame, 0, as shown inFigs. 1 and 3, the parallel bars of which move in grooves formed in theinner bar ot'the frames A A", their pivotal points being at C. Thearrangement of this sliding frame is such that when the table isextended, as shown in Fig. 3, it is moved inward sufficiently far toallow the leaf B to lie in the same plane with the rest of the leaves,and when the table is folded up it is to be moved outward to such' 5 anextent as to cause the leaves A and A to cover the upper edges of theleaves B B, and B", as shown in Fig. 2.

To the outer edges of the leaves A A there are hinged drop-leaves D D,which have secured to their under surfaces supportin gbraces 1) I),which, when the leaves are raised up, rest upon the lower end of aslotted bar attached to the frame A or A and hold the leaves intheirelevated position, at which time their upper surface is flush withthose of the other leaves. hen it is desirable to drop these leaves intothe position shown in Fig. 4 the free ends of the hooks are raised up tosuch an extent as to disengage them from the slotted catches D and theleaves fall into the position shown in Fig. 2. I have so far confinedmyself principally to a description of the mechanism attached to one endon] but it will be understood that the opposite end isprovided with aduplicate thereof, all of the parts being the same in construction andin the combinations and arrangements, the letters of reference being thesame in both.

For the purpose of affording additional support to the central leaves, Band especially to the inner edges, there is placed upon each one of thema folding leg, E, which is hinged to the under surface thereof, as shownclearly in Fig. 5, their upper ends opened out for use, resting in metalsockets E, attached to the under surfaces of the leaves. For the purposeof holding these legs in their opened positions they are proy'ided uponone of their surfaces with projections E upon which rest the free endsof the springs E E, as shown in Fig. 4, their action being such as tohold the legs in their opened position, and prevent them from beingmoved out of position when the table is being moved upon its casters.

When the table is folded up and not in use the legs EE occupy thepositions shown in Figs. 1 and 2 of the drawings, provision being madetherefor by making the leaves B B of greater width than those whichadjoin them. For the purpose of preventing the parts from beingseparated accidentally after they have been folded up hooks F Fareprovided, which are secured to the leaves A and A, the hooked ends ofwhich engage pins or screws, which are secured to the leaves A A, asshown in Fig. 1.

On reference to Fig. 3 it will be seen that all of the leaves composingthe upper surface of the table are hinged together, the effect of whichis to ca use them, when extended, to form an unbroken surface; and uponreferring to Fig. 2 it will be seen that when the parts are foldedtogether the leaves A and A form a small table with an even uppersurface, which may, if desired, be enlarged by the raising of the leavesD and D.

- I have described a table as composed of the parts and constructed asshown in the drawings; but it is evident that the form of theparticularparts may be changed to a considerable extent without departing from myinvention. It is apparent that the hooks used to hold the drop-leaves inposition may be used in other forms of tables, and it is also apparentthat the numberof leaves may be increased or diminished, and that themetal portions may be of malleableiron oranyotherkind of metal.

Having thus described myinvention, what I claim, and desire to secure byLetters Patent, 1s-

1. The combination of the fixed leaves A A, legs A A intermediatefolding leaves, outer drop-leaves, D D, frames A A, sliding adj ustablelegs B B, and leaf-supports B B for supportingtheintermediate leaves,the parts being constructed and arranged for operation substantially asand for the purpose set forth.

2. The combination of the adjustable sliding legs B B, swinging supportsB, curved bars B springs B and leaves 13 ,13, and B substantially as andfor the purpose set forth.

3. The combination of the adjustable sliding legs B B, the sliding barB, the guides B B and the bar A, provided with a stop, A, upon its outerend, substantially as and for the purpose set forth.

4. The combination of the foldingleaves B B and B the hinged swingingsupports B B, and the folding legs E E, whereby provision is made forholding said leaves in position for use, and for allowing the legs to befolded upon them when theyare folded together, substantially asdescribed.

5. The combination of the leaves B9B, the folding legs E E, metalsockets E E, attached to said leaves,and springs E E,substantially asand for the purpose specified.

6. The swinging leaf-support, consisting of the bars 13 B" and thehooked bars B B, the construction and arrangement of the parts being asdescribed, whereby the bars B are maintained in a horizontal positionwhen the table is extended to its full limit, and are allowed to fallinto a vertical position when the table is folded up, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
